Maintenance and Service Requirements for the 2014 John Deere S660

To ensure peak performance, service the 2014 John Deere S660 at regular intervals. Check the engine oil every 100 hours of operation. Replace it every 250 hours with a high-quality oil that meets the required specifications. Use only John Deere filters to maintain proper engine function and prolong its life.

Inspect the air filter every 100 hours and replace it when it appears clogged or damaged. Clean the pre-cleaner regularly to remove dirt and debris. This will optimize airflow and prevent engine strain.

Keep the hydraulic system in top condition by checking the fluid level and replacing the fluid every 1,000 hours. It is crucial to use the recommended hydraulic oil to avoid pump wear and ensure proper operation of all hydraulic components.

The combine’s cooling system requires attention every 250 hours. Check coolant levels and top off as necessary. Flush the system every 1,000 hours to prevent overheating and corrosion in the radiator and hoses.

Inspect the belts, chains, and pulleys regularly for wear. Tighten or replace them as needed to avoid failures during operation. Be sure to check the cleaning system’s belts to prevent crop buildup.

Test and calibrate the combine’s electrical system periodically. Ensure battery connections are clean and tight, and replace the battery every 4-5 years to avoid starting issues.

Keep the tires properly inflated to the recommended pressure levels. Over or under-inflated tires can affect performance, fuel efficiency, and cause uneven wear.

Always refer to the operator’s manual for specific service intervals and recommended products. Following the maintenance schedule will ensure the machine’s reliability and longevity.
